The International Domain Name (IDN) support in Firefox 1.0, Camino .8.5,
and Mozilla before 1.7.6 allows remote attackers to spoof domain names
using punycode encoded domain names that are decoded in URLs and SSL
certificates in a way that uses homograph characters from other character
sets, which facilitates phishing attacks.
